VETUS Bow Pro Boosted 210: specs, price and the boats it fits

The Bow Pro Boosted 210 is the top model in VETUS’s large-tube Boosted range, for boats of about 50 to 75 ft. It gives 463 lb of push with joystick control fine enough for small corrections, and a brushless motor with nothing to wear out but the zinc.

Fawcett Boat Supplies sells it for $8,745, with freight by truck quoted separately. Plan on about $635 to $1,634 for the tube, control panel, main switch and fuses. It draws on four batteries of its own at the bow, charged through the unit from the boat’s 24 V supply; those batteries and their cable come to about $3,815 to $4,034. Jump to the parts list.

VETUS rates it for 10 minutes at a stretch, and its user manual puts the real limit on battery charge. That’s far longer than the brushed Bow 220 of similar size. Change the zinc yearly and use a VETUS dealer for service to protect the three-year warranty.

The full spec sheet for a yard sits lower down, and the VETUS thruster review covers VETUS’s whole range.

How much of the install is yours

DIY 2 of 5: Wiring prep only. The yard fits the unit and does the hull work; you do the wiring prep.

DIY levels

  • Level 5: Owner install. No yard, no electrician.
  • Level 4: You fit it, electrician connects. You mount and wire it; a marine electrician makes the final connections.
  • Level 3: Split with the yard. The yard does the below-waterline part; you do the wiring.
  • Level 2: Wiring prep only. The yard fits the unit and does the hull work; you do the wiring prep.
  • Level 1: Yard job. A qualified professional does all of it.

You Yard Electrician. The bar is labor hours; a haul-out is a note.

How we rate DIY

You: 4 to 16 h Yard: 32 to 70 h Electrician: 2 to 4 h Plus a haul-out.

  1. Cut, bond and fair the tunnel; fit the gear leg, motor and propeller Yard 32 to 70 h The low end is two crew over two days, the job as owners describe it on the forums. The high end rises with boat length between two real billed figures: 32 hours at 35 ft, and the largest invoice we hold, 70 hours at 47 ft.
  2. Mount the battery box, switch and fuse holder; run and secure the cables You 4 to 16 h Our estimate. No maker times this step, and a first-time owner is slower than a yard, so the range is wide.
  3. Final connections at the battery and the motor, load test Electrician 2 to 4 h Our estimate. Nobody publishes a time for the final connections and test on their own.

Your part needs:Heavy battery cableCrimping big lugs

A qualified marine electrician should make the final connections and test them before first use. Hours are labor only.

Is it right for your boat?

What VETUS says 50 to 75 ft The maker's own range, from its listing
What our sizing says 54 to 80 ft Full thrust in 15 knots. The longest boat of each kind is in the table.

Our figure is the longest boat one unit can steer in a 15 knot wind. It is a range because each kind of boat catches the wind differently. Here a houseboat gets full thrust to 54 ft, and a catamaran to 80 ft. The maker gives one range for every boat.

The table below tries the VETUS Bow Pro Boosted 210 on each kind of boat, at every length that kind of boat is built in. The wind is 15 knots and the rules are the finder’s own. A length counts as a fit when the unit gives the thrust that boat needs at the bow and the maker lists it for that length.

A boat up to 10 percent past the maker’s range still counts here, as it does in the finder. So the table runs down to 45 ft and up to 80 ft, just past VETUS’s own range (50 to 75 ft).

The VETUS Bow Pro Boosted 210 against each kind of boat, in a 15 knot wind. Our sizing, from the finder’s own rules.
Boat Full thrust at 15 knotsStill a fit, in lighter wind
Pontoon & tritoon Not listed. A pontoon has no hull body between the logs to bore a tunnel through, and nobody sells one for these boats.
Sailboat 60 to 72 ft 73 to 80 ftfull thrust to about 14 knots at 80 ft
Houseboat 45 to 54 ft 55 to 80 ftfull thrust to about 10 knots at 80 ft
Catamaran 68 to 80 ft None
Trawler 59 to 72 ft 73 to 80 ftfull thrust to about 14 knots at 80 ft
Motor yacht 59 to 72 ft 73 to 80 ftfull thrust to about 14 knots at 80 ft
Bass & flats Not listed. Nobody sells a tunnel kit for these hulls, and a bass boat’s shallow planing bow has almost no depth to hold one.
Wake & ski boats Not listed. Nobody sells a tunnel kit for these hulls.
Express cruiser No length. More thrust than the boat needs.
Center console No length. More thrust than the boat needs.

Reading the two length columns. The first column is where one unit gives all the thrust the boat needs in 15 knots. The second is where the finder still lists it: the unit falls short of what the boat needs by no more than 10 percent, and gives the whole figure only in the lighter wind named. On a boat shorter than the first column’s shortest length, the unit is more than the boat needs.

It is sized for five kinds of boat here. For your own boat, the finder gives an answer that also counts your drive and who does the fitting. The compare page sets this unit beside others.

What it costs fitted

These totals are our estimate of a yard job: the unit’s price, plus a yard’s hours at $160 to $180 an hour, plus the batteries, cable and charger, plus the other parts the box does not hold. A Lifting the boat out of the water on a travel lift or a trailer so work can be done below the waterline. It is billed separately from the job itself. adds $800 to $3,860 at these lengths, with 5 to 7 days out of the water, worked from eight yards’ own rate cards. The hours come from what owners and yards report. Your own yard will have its own opinion. The cost page builds the same figures line by line.

How the batteries, cable and charger add up. We price a battery bank close to the thruster, as the makers recommend, with 10 to 20 ft of cable out and back: red for the positive, black for the negative, cut to length. The low end is the cheapest battery that meets the figure and the shorter run; the high end is a sealed (AGM) battery and the longer run. The charger is a NOCO GEN5X2 two-bank shore charger.

Batteries and lugs are priced at Fisheries Supply and the cable and charger at Defender, read 12 October 2026.

  • At 48 V: four 12 V batteries in series, at least 185 Ah each (VETUS’s minimum), $3,720 for all four; VETUS’s cable table gives 1/0 to 3/0 AWG, priced on 1/0 to 4/0 AWG, the nearest size cut to length: $95 to $314 for the red and black cable and the lugs; no charger, as the unit carries its own.

The sizing and the costs on this page are estimates, for guidance only and without warranty. They are no quote, and nobody has inspected your boat. Check them against the maker’s manual and your yard before you rely on them. Terms of use.

What else you buy

What follows comes from VETUS’s BOW55D installation manual 020522.11 r08 and the BOW PRO Boosted manual 020808.04 r09, May 2026 and February 2026, read 30 September 2026.

In the box
The unit assembled or in parts, the zinc anode, insulated gaskets, the drill template, the solenoid switches and the 5 A control fuse on the motor. BOW PRO: the thruster fuse in the connection unit.
Bought separately
The tunnel, the main switch (BATSW250 or BATSW600), the main fuse (ZE) and holder (ZEHC100), the cable, the control panel and its cable.
Charging
Every VETUS manual wants "its own separate battery or batteries" near the thruster, sealed if it shares the motor's compartment. The BOW PRO Boosted units carry a charger (12 V, 80 A) fed from the boat's bank, with a fused feed cable. The other manuals show an alternator and a battery separator on the wiring diagram and say nothing more.

The manual’s words, page 22 of the Boosted manual: “By connecting the 24 Volt battery bank to the MCVB boosted charge connection, the 48 Volt, battery bank is charged. An additional charging facility is not required.”

The “other parts” line in the estimate above is the priced parts below, $635 to $1,634 at Fisheries Supply’s prices on 30 September 2026. The batteries, cable and charger have a line of their own.

Draw, cable, fuse and battery, at each voltage

These are the maker’s own figures, at each voltage it is sold at. The cable is the size for the shortest run in the maker’s table. A longer run may need heavier cable, and the wiring calculator works that out for your own boat.

What holds up and what to weigh

Each point names the fact it rests on.

What holds up

  • It is sold at 24 V and at 48 V.The maker's and dealers' listings

What to weigh

  • The boat comes out of the water to fit it: it needs a tunnel bore below the waterline.The mounting: a bore through the hull, or a housing recessed into it

What the manual and listings say

This is the note we keep on the VETUS Bow Pro Boosted 210, written from the maker’s manual, its product pages and the dealer’s listing.

In the box: A charger is built in (12 V, 80 A), fed from the boat's own bank. Proportional: the joystick sets how hard it pushes. The thruster fuse sits in the connection unit.

Our note

A 24/48 V unit in a 250 mm tunnel, on four 12 V batteries in series. Boosted means the thruster runs on its own bank, which the boat's system charges through a built-in charger. The 250 mm manual prints no feed-cable table. It is brushless and proportional, so the joystick sets how hard it pushes instead of switching it on and off.

The installation manual rates it at 10 minutes (S2). The user manual says run time is mainly limited by the battery. The US press release's "unlimited runtime" appears in neither. The manual gives 275 A at 44 V (300 at 42) and an example battery of four 185 Ah 12 V batteries.

It calls for a 300 A main fuse and a 250 A fuse in the controller that must stay in place. It gives 1 AWG cable to 18.0 ft of total run. The June 2026 user manual cut its slow-blow fuse from 300 A to 250. The product page prints 213 A. Truck freight only from the dealer. The warranty runs three years and is claimed through the dealer only.

It is void unless an authorized VETUS dealer does the periodic maintenance, and labor, transport and lifting are excluded.
